Trim spaces from start and end of string

Question

I am trying to find a way to trim spaces from the start and end of the title string. I was using this, but it doesn\'t seem to be working:

title = title.repl         


        

Answer 1

This is what is suggested by JavaScript Architect/Guru Douglas Crockford.

String.method('trim', function (  ) {
    return this.replace(/^\s+|\s+$/g, '');
});

Note: you have to define "method" for Function.prototype.

Alternatively

String.prototype.trim = function () {
   return this.replace(/^\s+|\s+$/g, '');
};

title.trim();    // returns trimmed title

Observation

In recent browsers, the trim method is included by default. So you don't have to add it explicitly.

Major browsers Chrome, Firefox, Safari etc. supports trim method. Checked in Chrome 55.0.2883.95 (64-bit), Firefox 51.0.1 (64-bit), Safari 10.0 (12602.1.50.0.10).
